Here's another large bald bird from Africa (apparently featherloss is a big problem there for birds?): the Southern Bald Ibis (Geronticus calvus). These odd-looking birds breed in colonies amongst rocks and along cliffs where females lay 2-3 eggs which are incubated for 21 days before hatching.
In huge news for a tiny bird species five critically endangered Plains-wanderers have recently hatched at Taronga! With less than 200 Plains-wanderers left in the wild, Taronga and the Office of Environment and Heritage have a joint partnership to try and bring these birds back from the brink of extinction.
